Demand Controlled ventilation (DCV) is the rate of ventilation that is modulated over time based on sensor inputs from a CO2 sensor. The inputs may signal conditions such as level of air pollutans or occupancy. DCV offers two potential advantages: better control of indoor pollutant concentrations, and lower energy use and peak energy demand. At present, most DCV systems are based on monitoring and control of carbon dioxide (CO2) concentrations. Current research and case studies support energy savings and the cost-effectiveness of using DCV as an energy conservation measure.
